Information security incident response

Response to information security incidents (IS) is a structured set of actions aimed at establishing the details of an incident, minimizing damage from the incident and preventing the recurrence of an information security incident. 

In practice, there are several phases of incident response in the field of information security, namely: 

  • Analysis of network activity. The information security incident response team evaluates network traffic and diagnoses suspicious information systems.
  • Forensic analysis. Experts conduct a forensic express survey of all servers operating in the company, which are used by fraudsters, in order to establish the causes of attacks, move attackers across computer systems and networks.
  • Diagnostics of malicious code. The analyst carries out a fundamental static and dynamic analysis of the models of malicious code found during the response. The aforementioned enables experts to exclude its fixation in computer systems and avoid re-infection of the company's IT infrastructure. 

Briskinfosec IS Incident Response Mechanisms 

There is no doubt that the identification and response to incidents in the field of information security are the main areas of work for Briskinfosec. During the conduct, vulnerabilities in the IS are determined and all traces of hacker attacks and intrusions are found.

 Investigating and responding to information security incidents, a team of qualified Briskinfosec employees carries out a whole range of processes, consisting of certain successive stages: 

  • At the first preparatory stage, specialists carry out thorough operational work to ensure comprehensive protection of the organization's information system. Company members are informed about the need to support security measures.

  • Securing the situation and a comprehensive study of objects of information resources that are related to the incident.
  • Coordinating the process of neutralizing the impact of computer intrusions, the action of which influenced the occurrence of the incident. Our employees install a security system in such a way that the infection will not spread further. Reconfiguration of the information system begins with the aim of its further work without consequences.
  • The main point of the "removal" process is to bring the infected IP back to its original form. Specialists with the necessary qualifications will eliminate both malicious software and other infected system components.
  • Establishing the root causes of the incident and its undesirable consequences for the information system.
